Of those, the Tango cliques, Barrio Azteca and Texas Mexican Mafia are cited in the report as “Tier 1” gangs. These gangs have relationships with Mexican cartels, according to the report.

The report also points out that the Aryan Brotherhood of Texas and Aryan Circle are active in the Midland-Odessa and San Angelo areas. In February 2013, FBI and Homeland Security worked with DPS agents from Houston, Dallas and Midland to arrest an Aryan Brotherhood of Texas “general” who allegedly made threats against law enforcement.

DPS is required to report the threat of gangs in Texas annually, in accordance with Texas Government Code Chapter 421. A 2015 report has yet to be published on the DPS website.
